java.lang.AssertionError: CALL 'public final fun <get-currentComposer>

Question

我正在尝试使用 jetPack Compose 创建一个项目，我有它工作所需的所有依赖项，但是当我运行我的应用程序时，它抛出一个错误，我找不到解决方案

这是错误：

 java.lang.AssertionError: CALL 'public final fun <get-currentComposer> (): androidx.compose.runtime.Composer<*> declared in androidx.compose.runtime.ComposerKt' type=androidx.compose.runtime.Composer<*> origin=FOR_LOOP_ITERATOR

我添加的所有依赖项


 def jetpackDef = "1.0.0-alpha09"


  // Jetpack compose navigation
        implementation "androidx.navigation:navigation-compose:1.0.0-alpha04"

implementation "androidx.compose.ui:ui:$jetpackDef"
        // Tooling support (Previews, etc.)
        implementation "androidx.compose.ui:ui-tooling:$jetpackDef"
        // Foundation (Border, Background, Box, Image, Scroll, shapes, animations, etc.)
        implementation "androidx.compose.foundation:foundation:$jetpackDef"
        // Material Design
        implementation "androidx.compose.material:material:$jetpackDef"
        // Material design icons
        implementation "androidx.compose.material:material-icons-core:$jetpackDef"
        implementation "androidx.compose.material:material-icons-extended:$jetpackDef"
        // Integration with observables
        implementation "androidx.compose.runtime:runtime-livedata:$jetpackDef"
        implementation "androidx.compose.runtime:runtime-rxjava2:$jetpackDef"
        implementation "androidx.compose.runtime:runtime:$jetpackDef"


     buildFeatures {
        // Enables Jetpack Compose for this module
        compose true
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }


    kotlinOptions {
        jvmTarget = "1.8"
        useIR = true
    }

任何帮助将不胜感激，谢谢。

Answer 1

我通过设置 composeOptions 让它工作，当我有 kotlinCompilerExtensionVersion =“1.0.0-alpha08”时我得到了这个错误，而其余的库是 alpha09。

    composeOptions {
        kotlinCompilerVersion = "1.4.21"
        kotlinCompilerExtensionVersion = "1.0.0-alpha09"
    }

Answer 2

compose 版本 alpha09 似乎有问题，降级到 alpha08 应该可以。

Answer 3

对我来说 JuliusScrip 的回答并没有完全解决它：如果你在你的 build.gradle(:project) 文件中使用 ext.kotlin_version，你也需要更新它：

buildscript {
  ext.kotlin_version = "1.4.21"
  ...
}
